[X2go-User] X2Go problem

Hi,

I've installed x2go on both my client pc (Kanotix/Debian Stable) and my server (salineOS / Debian stable) I configured my router with a dyn-dns adress and a port forwarding to my server but cannot login with remote from my client PC. When I try x2go freezes or I get this message:

*Host key for server changed.*

*It is now: 4c:53:xxxxxxxxxxxxxxxxxxxxxxxxxxxxx*

*For security reasons, connection will be stopped*

It has worked before but now it doesn't anymore. I reinstalled the Linux on my server maybe this is the reason?

Could anybody here help me with that problem?

best regards Christopher
